It appears Google is making some updates to Google Friend Connect (which is why my Join our network button doesn't appear and why my Followers widget is cut in half).
If you go to the Friend Connect site, you'll notice if you have a Blogger blog that your blogs now appear in your list of sites, and that they seem to be bringing all of Friend Connects features to Blogger.
I'm hoping this'll mean change for the default commenting system in Blogger (hopefully powered by Friend Connect this time).
EDIT: Testing something out.
